Each alert class climbs one rung at a time on measured evidence. Any regression steps it back down, and a policy violation trips a breaker that has to be reviewed before it can climb again.
Requirement
Push autonomous remediation into the paths that page people today: alerts that resolve themselves, and a first responder that is an agent with a hypothesis already tested.
Promotion criteria (proposed)
Shadow to approve: proposals match what the human actually did, at least 95% over a fixed window.
Approve to auto: a run of clean executions with zero rollbacks.
Demotion is automatic; promotion is a reviewed decision.
Evidence and gap
Built in Hangar: HolmesGPT AI-triage on alerts. Your own burns: an order-api prod wipe and a provider restart that caused real data loss are exactly why this ladder has a breaker and a "never" tier. Proposal only: the promotion tracker.
